~Our Mission~
Building a Joyful, Vocal, and Involved Community through Song





On a mission to engage and inspire audiences through the transformational power of choral music, the Mission Peak Chamber Singers (MPCS) have long been part of the Bay Area choral scene. Established as the Ohlone Chamber Singers in the 1980’s, Mission Peak Chamber Singers struck out as an independent non-profit organization in 2014 after California community colleges withdrew support for choral arts. Now reliant upon the generosity of donors, fundraising and concert ticket sales, MPCS champions the cause of music as a community enterprise and as a medium of social change. Music is our gift to you, and we recognize and are deeply grateful for the steadily increasing support from our audience and donors! 

Each year’s season gets underway with the beloved and long-standing "Christmas at the Mission" December concert, followed by lighter musical fare in March and a season finale concert in May. This past August, our community broke new ground with an invitation to members of the public to join a non-auditioned, fee-free, open ensemble, where people of all ages and all backgrounds can share the joys of singing with a group in a welcoming and comfortable environment. Thus, the East Bay People’s Choir (EBPC) was born! With growing support from new and loyal enthusiasts, we look forward to continuing performances that bring passionate excellence in the choral art to audiences this season!

Sid Quinsaat

Associate Director

Sid truly believes in the power of music to heal and make peace. It encourages people to be vulnerable and to be their true selves, while simultaneously listening to others, ensuring that their voices work together to create more beauty in the world. This belief propelled Sid into work that they believed would help make a positive impact.

Their first job 5 years in the area was for the Sierra Club to helping to raise money to stop deforestation in Northern California. After that first summer in Oakland, Sid began working for the Oakland Youth Chorus where they would remain for the next three years, teaching music and working with students from Kindergarten through Middle School all throughout Oakland. Afterwards Sid began directing choirs and musicals at Moreau Catholic High School in Hayward, which led them to opportunities at St. Ignatius in SF, and ultimately Piedmont High School. Sid continues to sing in the San Francisco Choral Artists and studies voice with James Toland, and is so grateful to be doing the thing they love the most for work.
